Objects
Objects are the basic units that the Epic Edge™ prints. An object can be either a line of
text characters, a bar code, a landscape graphic, a landscape line, or a bitmap dot line.
Each of these objects has different rules relating to them, as discussed below.
Objects can also be either active or complete. An active object is one that is still
receiving the data that composes it. A completed object is one that has been terminated.
A line of text that has not yet received a line feed or carriage return is an example of an
active object. Until a terminator character, like a line feed, is sent, more text characters
can be added to the text object. Bar code and graphic objects do not require special
terminator characters (such as line feeds). Instead, they are considered complete as
soon as they receive the correct amount of data.
